What model is my Craftsman lawn mower?
For a Craftsman riding lawn tractor like model 917271054, the model number is printed on the product identification label; it’s commonly found under the seat area or on the frame. Once you have the model number, you can match it to the parts diagrams and specifications in the owner's manual.
Check these common label locations first (wipe off grass and dirt so the numbers are readable):
- Under the seat pan or on the seat support bracket
- On the frame rail near the rear wheels
- Near the engine compartment on the chassis
- Under the hood area on the frame (if equipped)
- Near the footrest area on the frame
Craftsman model numbers are often a 9-digit format (sometimes shown with a dot in manuals). For this tractor, the manual shows it as 917.271054, which matches 917271054.
| What you see on the label/manual | What it means |
|---|---|
| 917.271054 | Same model as 917271054 |
| 917271054 | Model number used for parts lookup |
| Serial number | Identifies your specific unit; not the model |
Using the exact model number ensures you get the correct parts for your deck size and configuration (this model is a 42-inch mower deck). It also helps you pull the right diagrams for items like blades, mandrel assemblies, tires, and electrical parts.
- Use the model number to select the correct parts diagram section
- Compare your part visually to the diagram before ordering
- If you’re working on the 42-inch deck, confirm deck-related parts by diagram callout

What size belt is on a CRAFTSMAN 917271054 riding lawn mower?
Your Craftsman lawn tractor model 917271054 uses more than one belt, so the “belt size” depends on whether you mean the ground drive belt (tractor moves) or the mower deck belt (blades spin). Use the belt routing and parts list in the Owner's manual to identify the correct belt for your exact deck and drive setup.
Most riding mowers like the Craftsman 917271054 have at least these belt types:
- Ground drive belt: engine to transaxle; controls forward and reverse movement
- Mower deck belt: engine PTO to deck pulleys; drives the cutting blades
- Deck idler/guide components: affect routing and tension (a wrong belt length slips or won’t tension)
Because “1/2 in. x 101 in.” style descriptions vary by routing and pulley layout, we match by model and diagram:
- Confirm the symptom: won’t move (drive belt) vs. won’t cut (deck belt)
- Verify deck size and configuration; the manual shows a 42-inch mower deck section
- Use the belt routing diagram and the belt’s part number from the model’s parts list
- Compare related deck hardware to ensure you are in the right diagram section
These parts appear in the 917271054 mower deck listing and help you confirm you are viewing the correct deck diagram before selecting a belt:
| Deck component | Example part (from this model’s parts list) | What it indicates |
|---|---|---|
| Mower housing/deck shell | Lawn mower housing 548102301 | You are in the mower deck assembly section |
| Mandrel pulley | Lawn tractor mandrel pulley 532173436 | Belt rides on mandrel pulleys for blade drive |
| Deflector shield | Lawn tractor deflector shield 532130968 | Confirms deck configuration and safety discharge parts |
A belt that is slightly too long, too short, or the wrong profile can cause slipping, poor cut quality, thrown belts, or premature idler and mandrel wear. Matching the belt by the 917271054 diagrams prevents repeat repairs.

What year did Craftsman make the 917271054?
Craftsman model 917271054 was produced as part of the LT-series era commonly seen in the early 2000s; the exact build year for your specific tractor is identified from the serial number on the tractor, not from the model number alone. Use the date-coding guidance in the 917271054 owner's manual to decode it accurately.
Look for the model and serial number label (commonly under the seat or on the frame near the seat). Once you have the serial number, use the date code format described in the manual.
- Park on a flat surface, set the parking brake, and remove the key.
- Lift the seat and inspect the frame area for the ID label.
- Confirm the model reads 917.271054 (sometimes printed with a dot).
- Write down the full serial number exactly as shown.
- Use the manual’s serial/date code section to translate the serial into a manufacture date.
The documentation confirms the tractor’s model identification and parts breakdown for 917.271054, and it lists engine configuration details used on this model family.
| Item | What it tells you | Where to use it |
|---|---|---|
| Model number (917271054) | Identifies the tractor design and parts list | Ordering correct parts and diagrams |
| Serial number | Identifies the specific unit’s build date | Determining the exact year |
| Engine listing | Helps match tune-up and engine parts | Engine service and troubleshooting |
The build year affects small but important fit details such as deck hardware, steering linkage revisions, and electrical components like the starter solenoid. Getting the year right helps you avoid ordering the wrong blade, mandrel, or chassis parts.
